Do you buy a new remote every six months when its batteries die? Because Apple and Nike expect you to pay another $30 for a new Nike+ receiver when the battery on your current one dies. Fuck. That. Instructables has a how-to on how you can replace it with $5 worth of materials and 10-15 minutes worth of work. Since you're using electrical tape to secure the battery, the inside may not look as pretty as it did when you bought it; but your insides are pretty disgusting as well, so who are you to judge?
